There has been lots of discussion about lens IS versus IBIS and which is best, but I've just found what I think is the cream of the crop for stabilisation. The above video was shot 100% hand held using a Panasonic GX8 plus a Canon 24mm f/2.8 IS lens fitted via a Metabones Canon EF > m4/3 0.71x crop AF adapter. The lens IS is switched on as is the IBIS in the Panasonic. As you can see after editing the footage in iMovie and adding that apps. IS function as well, the footage is rock solid and looks just like it was shot on a tripod.
I've never produced anything better than this, including with the 5-axis stabilisation of cameras like the Olympus OM-D Mk II. This is VERY impressive and even more so when the fact that I was using a Canon EF lens is taken into consideration. So why is this so good?
Well it seems that using this adapter with the GX8 and a Canon lens fitted, both the lens IS and the IBIS are switched on and work independently of each other, therefore letting two separate systems work at the same time. Panasonic are developing firmware for their OIS lenses that enable that to be used in conjunction with the GX8 bodies, but I think this is slightly different because of the adapter. Somehow the two forms of stabilisation seem to be working unaware of the other. At least that's the theory and I have no evidence to back it up. There is of course the evidence of the amazing rock solid footage however and that is indicating that something is going on that creates stability that even the sophisticated 5-axis systems that Olympus and Sony have come up with can't match.
I suspect that this may be a happy accident and in fact something that maybe wouldn't have been predicted. However I'm obviously not complaining. Those of you who are observant will also have noticed the waves on the river indicating that I was working in a very strong wind. It was in fact close to a gale, which makes the results even more remarkable. So a camera / lens /adapter combination that enables footage to be shot in a gale, hand held. Pretty impressive stuff, considering that I wouldn't have got footage like this even with a heavy pro video tripod. Wind like that always shakes the camera around, unless it's attached to something with concrete blocks attached!!
In terms of how I worked with it, I used the EVF and had the camera pressed against my face and I have to say the image I was seeing looked very still in the viewfinder, so I was aware that it was working very well. It obviously works for stills as well, though it that wind slow shutter speeds would have resulted in some blurred areas, particularly in the water.
So all in all a very successful experiment. I would mention as well that my 25-105mm f/4 Canon zoom does exactly the same at the wide end, though the prime lens does give slightly sharper results. It's an unusual combination, but very useful indeed for my stock video clip production. I will be producing individual clips from this footage and uploading them the stock websites that sell my video. And I can contemplate shooting a lot more very stable video without having to cart a tripod around. What's not to like!!
